I am depressed

Well, might set a long term goal of decluttering. Do not be discouraged if you realize it may take several days or weeks because the time will pass either way.
I do not know how big a mess we are talking here. Usually cleaning up hoards of junk does not happen overnight.

I would say first thing is start in one room. Create a small area in the room to organize smaller things. Right away you can see results and that can keep motivation going.

With really bad hoarding, yeah it seems overwhelming and hopeless. BUT, just work on small cycles of ridding junk and organizing important stuff. Eventually it gets to where even if you throw away very little, at least what is left is organized.

Close your eyes and throw it all out.
Or Set yourself a strict limit
Example:
newspaper collection: maximum 10
jars and containers collection maximum 20

it should help you get rid of the mountain of things you don't really need

Remember to de-clutter often. As Mari Kondo method suggests - whatever does not bring you "joy" to possess - doesn't have place in your home anymore. I am not a 100% Mari Kondo follower, I just got inspired from her to think more inquisitively if I really REALLY need this and it helped me.

A room that breathes feels better than a room full with boxes and what not.. :)

You should talk to a counselor I think. Maybe look for strategies to help you deal with all bad stuff.

It seems like I'm always getting rid of something.

Seek professional help? A therapist.

You should talk to a Therapist

Get a bunch of large trash bags and throw it out.

Trauma therapy.
